Transformer

a device that transfers electrical energy through electromagnetic induction from one circuit to another through inductively coupled conductors which are the transformer's coils.

He demonstrated that applying an alternating current in one winding creates a changing magnetic field which, in turn, induce an electric current to the other winding.

He developed the first reliable commercial transformer

provides a path for the magnetic line of flux.

which receives energy from the AC source.

receives energy from the primary winding

and delivers it to the load.
